Muffler

how is the fmf titanimun 4 muffler that they make. I'm lookin for a lil more horsepower than my mega max but still want to use the same header. Other mufflers fit on the fmf headers?

If you have the FMF megamax full system the header won't fit anything else unless you cut and bend it. I ran the megamax system on my 300 until the silencer fell off, and I lost it during a race. I went back to the stock header and an HMF slip on. This made more power than the FMF ever did, I jumped from a 128 main with the FMF to a 135 with the HMF if that will tell you anything. With 20" rear tires and stock gearing I'd hold my own/fall off a bit against a stock 400 until he hit 3rd gear. Sounds odd that a slipon will make more power than a full system, but it is just designed that much better.
